The Claim

Cooling and reheating 200 grams of wheat pasta for 24 hours at 4°C increases its resistant starch content from approximately 8.0 to 12.9 grams per 100 grams and reduces the postprandial glycemic rise by 40% in adults with type 1 diabetes using insulin pumps, without increasing the risk of early hypoglycemia under standard bolus calculator dosing.

Cause and effect

In plain English

Cooling and reheating wheat pasta changes its starch structure, resulting in 40% less blood sugar rise after eating, without increasing the risk of low blood sugar in people with type 1 diabetes who use insulin pumps.

See the scientific wording

Cooling and reheating 200 grams of wheat pasta for 24 hours at 4°C increases its resistant starch content from approximately 8.0 to 12.9 grams per 100 grams and reduces the postprandial glycemic rise by 40% in adults with type 1 diabetes using insulin pumps, without increasing the risk of early hypoglycemia under standard bolus calculator dosing.

Why this might work

When pasta is cooled and then reheated, the starch inside it rearranges into tight, crystal-like structures that the body cannot break down easily. This means less sugar is released from the food as it passes through the gut, so blood sugar rises more slowly and stays lower after eating. The insulin dose given before the meal matches this slower sugar release, so blood sugar doesn’t spike or drop too low.

  1. Study: Does Resistant Starch Formed by Cooling Pasta Decrease the Postprandial Glycemic Response in Type 1 Diabetes? A Randomized Single-Blind Crossover Study

    Chilling and reheating pasta changes its starch so your body digests it slower, which means less sugar rushes into your blood after eating. This study showed that people with type 1 diabetes who ate cooled-and-reheated pasta had much smaller blood sugar spikes — without getting low blood sugar from their usual insulin dose.
